Hi,
So, trying to force external behavior in Teams while avoiding that guest status. It is not straightforward. Teams and Azure AD handle roles based on the backend user identity and how federation is set up. You cannot really force a user to switch to external if they are already listed as a guest in your Azure AD tenant. Still, there are some steps you can take to work around it.
First off, check your Azure AD users. Head over to Azure AD, then Users, and look under Guest users. See if the user shows up with that (Guest) label next to their name. If they do, yeah, they are already added as a guest. That means they will act like one in Teams and everything else.
Now, if you want them to come across as purely federated instead, you might need to remove the guest account from Azure AD. Just be careful with that. Once it is gone, they should appear as external. But this only works if your federation is set up right. It could mess with their access to any shared resources you have going on.
Kind of related, verify those federation settings in the Teams admin center. Make sure your tenant is set to trust the other one. Federation basically lets external folks join without you having to send guest invites every time.
Oh, and when you add users, always use their primary email address from their own tenant. That way, things match up properly and avoid extra complications.
